A group of Brazilian researchers has presented an innovative proposal to resolve a decades-old debate among theoretical physicists: How many fundamental constants are needed to describe the observable universe? Here, the...

Researchers have developed a new hyperspectral Raman imaging lidar system that can remotely detect and identify various types of plastics. This technology could help address the critical issue of plastic pollution in the...

Leveraging the principles of quantum mechanics, quantum computers can perform calculations at lightning-fast speeds, enabling them to solve complex problems faster than conventional computers. In quantum technology appli...

An Alabama woman underwent a transplant procedure to get a new kidney from a gene-edited pig.

Researchers have uncovered how visual information is processed across the brain's complex and flexible networks. One study showed visual signals are selectively targeted or broadly broadcast, challenging the idea of a si...

X-rays are radiated by matter hotter than one million Kelvin, and high-resolution X-ray spectroscopy can tell us about the composition of the matter and how fast and in what direction it is moving. Quantum calorimeters a...

String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a "provable" phenomenon. But a team of physicists has now taken a significant step forward in val...

The updated version of the World Magnetic Model was released on Dec. 17, with a new prediction of how the magnetic north pole will shift over the next five years. Here's why it was changed.

Infants' heart rate rhythms are closely linked to their early vocalizations, including coos, babbles, and emerging words. Researchers found that babies were most likely to produce sounds when their heart rate reached a p...

Researchers have found that ketamine's antidepressant effects target astroglia, a type of brain support cell, rather than neurons, challenging conventional views. Using zebrafish, scientists observed that ketamine suppre...

While investigating a mysterious radiation signal unlike any seen before, astronomers may have uncovered a rare pair of binary supermassive black holes with a truly monstrous appetite.

Researchers have developed lipid nanoparticles (LNPs) that cross the blood-brain barrier (BBB) and precisely target brain cells, a major step toward treating neurological diseases like Alzheimer's. By attaching short pep...

When will MDMA be approved for therapy? Major trial issues may stand in the way, psychiatrist Dr. Albino Oliveira-Maia says

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of atoms. This has been...

Large language models (LLMs) can identify when they are being given personality tests and adjust their responses to appear more socially desirable. Researchers found that LLMs, like GPT-4, showed exaggerated traits such ...

Tiffany Taylor, professor of microbial ecology and evolution at the University of Bath in the U.K., recommends the books that shaped her career and her outlook on life.

A Phase I clinical trial has demonstrated the long-term safety of neural stem cell transplantation for chronic spinal cord injuries. Researchers followed four patients for five years, with two showing sustained neurologi...

Computer modeling suggests Saturn's rings are billions of years older than previous research suggests -- but the new findings are up for debate.

With a 29% saving, these tech-packed binoculars are at the lowest price they have been in years.

Biological nanopore technology revolutionised DNA sequencing - now it has been adapted for analysing alcoholic drinks, providing a quick test for quality and safety

The biodiversity, climate, health, water and food crises need to be addressed together rather than regarded as separate issues, urges a major report

About 30 years ago an "ideas guy" and a team builder joined forces to search for the invisible bulk of existence.
